Implicit Function Grapher

For a system having multiple inputs x and outputs y, the partial coherence is the coherence computed between any individual input and the output when the effect of all other inputs is removed from the output by a linear least squares prediction. This coherence obeys the usual inequality, and will...

The anonymous function handle feature of ML 7 is a long-needed feature, and one that I have longed for since I began writing scripts in early ML 6.Unfortunately, I am still forced to use ML 6 most of the time, so I came up with a way to create "psuedo-anonymous" function handles: that is,...

Function takes a picture as an argument (suitably should contain only one object whose centroid is to be obtained) and returns the x and y coordinates of its centroid.

I was not able to get the peaks from my experimentally obtained data because of its random nature. As a result the findpeaks() defined in Matlab library was not giving results as expected. Hence I made a code which will help findpeaks() help detect the peaks more accurately.It basically averages...
